Bitch boy's Favorite

Korean BL with childhood friends. Uke is a buff salaryman and seme is a younger college srudent who has been in love with him. Seme confesses but uke doesn't take him seriously at all. Uke also somehow got into anal masturbation because of a medical exam and the last chap I remember reading was uke masturbating with a dildo and seme walking in on him. It's fairly new pls help me find it, I'm dying

Istfg if he gets mad at Cain then I demand a refund on my time
